Hosta plant named ‘Hands Up’

ABSTRACT

A new and distinct  Hosta  cultivar named ‘Hands Up’ is disclosed, characterized by a distinctive upright plant habit, large flowers, vigorous plant habit and strong foliage, with good resistance to environmental stressors. The near variety is a  Hosta , typically used for outdoor ornamental purposes.

Latin name of the genus and species: Hosta hybrid.

Variety denomination: ‘HANDS UP’.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as an induced mutation using the known chemical colchicine, of Hosta hybrid ‘Praying Hands’ unpatented. ‘Hands Up’ was discovered by the inventor, Marco Fransen, a citizen of the Netherlands in October of 2008, at a research facility in Ter Aar, The Netherlands. The intent of the breeding program was to create new tetraploid Hosta hyrids with stronger foliage and plant vigor.

Directly after discovery of the tetraploid mutation, the inventor initiated cultivation in tissue culture, during October of 2008, in a commercial laboratory in Iribov Heerhugowaard, the Netherlands. ‘Hands Up’ was first propagated in the same commercial laboratory in Iribov Heerhugowaard, the Netherlands by tissue culture. Subsequently ‘Hands Up’ has been reproduced by micro-propagation and has shown that the unique features of this cultivar are stable and reproduced true to type through several generations.

SUMMARY OF THE INVENTION

The cultivar ‘Hands Up’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hands Up’ These characteristics in combination distinguish ‘Hands Up’ as a new and distinct Hosta cultivar:

-   -   1. Distinctive, upright plant habit.     -   2. Thick foliage.     -   3. Large flowers.     -   4. Vigorous plant.

COMPARISON TO PARENT

Plants of the new cultivar ‘Hands Up’ are similar to plants of the parent; Hosta hybrid ‘Praying Hands’ in most horticultural characteristics, however, plants of the new cultivar ‘Hands Up’ are more vigorous and produce thicker, stronger leaves than the parent variety. Additionally, the new variety produces larger flowers than ‘Praying Hands’. Leaves of ‘Hands Up’ have a wider variegation on the margin than ‘Praying Hands’.

COMMERCIAL COMPARISON

The most similar commercial Hosta hybrid variety available to compare to ‘Hands Up’ is the parent variety, as the very strong upright habit is not commonly found in Hostas.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Hands Up’ grown outdoors. This plant is approximately 6 months old, shown in a 1 liter pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
